I took my Yamaha R-1 to California Performance Iron for a thorough safety inspection, clutch and service. They have great customer service and have great knowledge of motorcycles.

Chopper Guys CPI specializes in custom built frames and fabrications. We make some of the strongest frames in the world. We were the first company to make a production wide tire frame for Harleys! Please view our custom FXR frames below:

Chopper Guys CPI can custom fabricate parts including oil bags, gas tanks, and anything with sheetmetal! California Performance Iron can create custom CNC parts, the definition of CNC is: CNC means Computer Numerical Control. This means a computer converts the design produced by Computer Aided Design software (CAD), into numbers. The numbers can be considered to be the coordinates of a graph and they control the movement of the cutter. In this way the computer controls the cutting and shaping of the material.

Yes, but standard rates will apply for shipping. If you choose to reserve a custom built frame and have it shipped you will be required to pay the shipping fees. Fees vary on weight and distance. Please view our custom FXR frames below:
